Banger Sphere

Carl's thrown finisher in the weasel ambush, deployed the moment he has something to aim at.

Story so far

Carl nails a weasel with a banger sphere at the close of the trailside fight, after dropping a Smoke Curtain, kicking several of the pack away, crushing one underfoot against a tree, and casting Fear. The sphere comes out only once he has multiple visible targets — the invisible Night Weasels having been revealed first by damage and then wholesale by Mongo's Earthquake attack.

It is one item among an armory of them, and the fight ends quickly afterward, mostly on the strength of the two Were-Castors' teeth and blades.

Role

Thrown explosive in Carl's kit, used as the closing beat of the night-weasel ambush.
